Web-based Management
The Modular Switch provides an embedded HTML web site residing
in flash memory. It offers advanced management features and allow
users to manage the Modular Switch from anywhere on the network
through a standard browser such as Microsoft Internet Explorer. For
more information, See Section 5 Web-Based Management.
SNMP Network Management
SNMP ( Simple Network Management Protocol ) provides a means
to monitor and control network device, and to manage configurations,
statistic collection, performance, and security.
Data is passed from SNMP agents, which are hardware & software
processes reporting activity in each network device to the
workstation console used to oversee the network. The agent return
information contained in a MIB ( Management Information Base ),
which is a data structure that defines what is obtainable from the
device and what can be controlled.

RS-232 Console
This Console port is used to connect a management station or
terminal with the switch. Out-of-band management means go
through the RS-232 port. For more information about switch
management, see Section 4 “ Connecting to the Network ”.
Software Concepts
StaticAddress
This feature allows you to enter the addresses that will not be aged
out. It can confine users on certain ports specified by the system
manager, so that they cannot switch to other ports.
Spanning Tree
Spanning Tree Protocol (STP) is an industry standard that prevents
loops configurations in switched networks. The Spanning Tree
algorithm creates a single path through network by making sure that
if more than one path exists between parts of a network, only one of
those paths is used.
This also permits multiple interswitch links to remain active for data
transport while operating in conjunction with the Spanning Tree
algorithm. The IEEE 802.1d Spanning Tree Protocol support for
redundant backbone connections and loop-free networks simplifies
network configuration and improves fault tolerance.
11

Virtual LANs ( VLANs )
A VLAN is a group of switch ports designated by the switch as
belonging to the same broadcast domain.
This feature allows workgroups to be defined on the basis of their
logical function instead of their physical location, and does not
require recabling. It also enables you to configure port-based VLANs
to help isolate broad- cast traffic and increase security, so as to
increase bandwidth to each station.
VLAN also helps you create limited broadcast domains, to prevent
traffic from being forwarded to stations where it is not needed.
Port Trunking
Port Trunking allows you to build higher bandwidth connections by
aggregate several ports into one single group.
Additionally, it may be more cost-effective to trunk multiple lower
speed links than to underutilize a gigabit port. Available copper links
and supported distances are more pervasive for lower speed links.
For example, 100Mbps NICs and switch ports are less expensive
than 1Gbps equipment.
Port trunking also allows end users to protect their investment in
existing infrastructure by reusing current equipment.
SNMP
( Simple Network Management Protocol ) A widely-used network
monitoring and control protocol. Data is passed from SNMP agents,
which are hardware and/or software processes reporting activity in
each network device ( hub, router, bridge, etc. ) to the workstation
console used to oversee the network. The agents return information
contained in a MIB ( Management Information Base ), which is a
data structure that defines what is obtainable from the device and
what can be controlled ( turned off, on, etc.). Originating in the UNIX
community, SNMP has become widely used on all major platforms.
12

Port Mirror
Port mirror allows user to define a destination port and a target port ,
all the packet on the target port will be copy and resend to
destination port, it make user can monitor the packet and won’t
effect the bandwidth of target port.
IGMP
Internet Group Multicast Protocol (IGMP) is used to support
real-time applications such as video conferencing or streaming
audio. IGMP allow you to query for any attached hosts who want to
receive a specific multicast service. The switch looks up the IP
Multicast Group used for this service and adds any port which
received a similar request to that group. It then propagates the
service request on to any neighboring multicast switch to ensure
that it will continue to receive the multicast service.
Port Security
Port Security allow you to restrict specific MAC addresses to reside
in some port. The mean is only packet that with pre-defined MAC
address will be received by the port. It allows user by manual input
the MAC address table.
Priority
There are two priority queues ( high and low ) on each port. Each
port arbitrates between two transmit queues ( high and low priority ).
The arbitration uses weighted round-robin between the high and low
priority queues, and you can adjust this weight.
Broadcast Storm Filter
Storm Filter can avoid any flooded data packets. This feature
prevents the bursts of broadcast traffic. Excessive broadcast
packets ( Broadcast Storms ) can be filtered in our managed switch
by enabling the "Broadcast Storm Filtering" option.

Network Configuration
This chapter provides 3 network configuration examples by using
the Modular Switch:
 Collapsed BackboneApplication
 Departmental Bridge Application
 Virtual LAN (VLAN) Application
The switch provides versatile configuration options for the network. It
is ideally suited as a workgroup or segment switch in a network; it
aggregate traffic from workgroup switches, or provide dedicated
100Mbps to servers with bandwidth-intensive applications. And
because all Fast Ethernet ports auto-negotiate for operation at 100
Mbps or 1000Mbps ( Gigabit ) the switch is perfectly suited to an
evolving network environment where demand for network speed is
increasing.
Collapsed Backbone Application
For small network where substantial growth can be expected in the
near future, this switch is an ideal solution supporting backbone
connectivity.
The switch can be used as a standalone switch for a group of heavy
traffic users. Switching is brought to the desktop either through a
single end-station per switch port or through a multi-port hub.
A 100 Mbps server is connected to a port, providing end stations
high-speed accessibility to its applications. This configuration
provides dedicated 100 Mbps connections to the network center, to
the server, and the most up to 24 users.
14

When the network needs expansion, you can simply daisy-chain the
switch to any IEEE 802.3 ( Ethernet ), IEEE 802.3u ( Fast Ethernet ),
IEEE 802.3z ( Gigabit Ethernet ) compliant hub. This switch can also
cooperate with a wide range of networking devices (e.g., firewall
routers and printer servers) added to the network.
Figure 3-1. Collapsed Backbone Application
DepartmentalBridge
For enterprise networks where large data broadcasts are constantly
processed, this switch is an ideal solution for department users to
connect to the corporate backbone. The Modular Switch used as
segment switch can alleviate user contention for bandwidth and
eliminate server and network bottlenecks. All ports can connect to
high-speed department servers that need high bandwidth. This
switch provides parallel communications between each of its ports,
which can run up to 200 or 2000Mbps at full duplex.
The Switch makes key servers available to more users by allowing
multiple conversations to occur concurrently, thereby significantly
expanding overall network throughput. Moreover, this switch eases
supervision and maintenance by allowing network manager
centralize multiple servers in a single location.
15

Figure 3-2. Departmental Bridge Application
NOTE: Full-duplex operation only applies to point-to-point access
(for example, when attaching the switch to a workstation, server, or
another switch). When connecting to hubs, use a standard cascaded
connection set for half-duplex operation.
16

IEEE 802.1Q VLAN Application
The switch support up to 4095 port-based 802.1Q-compatible virtual
LANs (VLANs).
Port-based VLAN Workgroup
You can group the switch ports into broadcast domains by assigning
them to the same VLAN to increase network capacity and
performance. With network segmentation, each switch port connects
to a segment that is a single broadcast domain. Packets received in
one VLAN can only be forwarded within that VLAN.
VLAN allows the grouping of end stations logically, based not on
physical location but on business policies such as job function or
department. Members of a group can be dispersed throughout a
facility - they do not have to be connected in close physical
locations.
Hence, group members can coordinate their data communication
requirements regardless of the actual working locations; and the
logical network can extend to any point you want it to. Moreover,
VLAN groups can be modified at any time to add, move or change
users without any re-cabling.
Figure 3-3. VLAN Workgroup Application
17

Shared Server
The switch compliant to the IEEE802.1Q tagging VLAN standard
allows ports to exist in multiple VLANs for shared resources, such as
servers, printers, and switch-to-switch connections. It is also
possible to have resources exist in multiple VLANs on one switch as
shown in the following figure.
Figure 3-4. Shared Server
In this example, stations on different VLANs share resources. As a result,
VLAN 1 and VLAN 2 can access VLAN 3 for printing. The broadcasts
from ports configured in VLAN3 can be seen by all VLAN port members
of VLAN3.
